ZerO2 Alert Oxygen Indicator

The ZerO2 Alert unit is a simple but effective method of indicating that oxygen levels remain low enough to effectively destroy insects during anoxic treatment.

The indicator has an oxygen sensor that is activated when inserted into the device. The LED on the ZerO2 Alert will flash red when oxygen levels are above safe treatment levels. Once the container is sealed, the LED should in due course flash green to indicate that oxygen scavengers and/or gas flushing have decreased the oxygen levels enough for treatment to commence.
